This is a stupid but frustrating problem! I have a Gateway Millenium keyboard. Up until a few days ago, all was well, but suddenly, the decimal point key in the number pad is remapped to run the function "default email application" (like the hotkey button at the top of the keyboard. I rely on this numpad a lot, so I really need to remap this. I'm guessing there is a layout in the registry??
What I've tried...
Using the Millenium keyboard function mapping (only allows you to remap the special keys at the top)
Uninstalling and reinstalling the keyboard (no new driver available)
